Definitions
- the invention relates to a light metal rim for motor vehicles with a rim bed with an outer and an inner rim flange and a wheel disc with spokes.
- Alloy rims for motor vehicles are increasingly replacing steel rims, not least because of their appearance. This is essentially determined by the construction of the rim, in particular by whether the rim is constructed in one piece or in several parts.
- DE 195 33 612 A1 relates to a vehicle wheel with a rim which is formed from a thin-walled and thus weight-reduced rim body with an outer and inner rim flange and a stiffening body in the region of at least one rim flange which is at least partially supported on an outer edge region thereof .
- the stiffening body ensures the required rigidity of the rim.
- DE 33 16 738 A1 describes a multi-part (two-part) light-alloy rim which is formed from a wheel disc (wheel disc) and a rim base which is detachably connected to it.
- the rim base has a circumferential web formed in the radial direction towards the axis of the wheel plate for overlapping and screwing with the peripheral edge area of the wheel plate, whereby in addition to the non-positive screw connection means for improving the fatigue strength, the same means for positive connection are provided.
- the screw connection means are visible on the outside of the rim and thus determine its appearance.
- the subject of DE 38 22 852 A1 is a two-part light-alloy rim, which has a wheel disc with a rim ring integrally formed on the inside of the wheel with an inner rim flange as part of the rim well and a ring connected to the outside of the wheel disc with an outer rim flange.
- the ring is - 2 - screwed to the wheel disc.
- the connecting screws on this rim are also visible on the outside.
- DE 93 09 706.9 describes a one-piece aluminum rim formed with three spokes, which is provided with a second so-called center, which is detachably arranged on the outside of the rim, for changing the rim design.
- This center can be fastened in the area between the outer rim flange and the wheel disk by means of screw-on receptacles which can be screwed onto these.
- the design of this one-piece fig is essentially determined by the screw-on center and the receiving elements. The load-bearing wheel disc is invisible.
- the light alloy rims described above are not only advantageous because of their low weight compared to steel rims, but also serve to an increasing extent to improve the appearance of the vehicle. Contributing to this in particular is a visible multipart structure of the rim and the visible screwing of the wheel disc to the rim base or with a ring with an outer rim flange with the screws arranged concentrically to the hub of the fig.
- rims are complex and weight-intensive than one-piece rims and make the diameter of the wheel disc appear smaller, which prevents a sporty appearance in connection with lower tires.
- a static design of the multiple parts is necessary.
- the flange protruding over the wheel disc has proven to be disadvantageous in that the inserts can be damaged even if the flange is hit lightly by an obstacle. Furthermore, high demands must be placed on the material with regard to the tensile forces that occur. As a result of - 3 - Clamping through the flange on the wheel disc requires that the wheel disc and also the inserts are manufactured with high tolerance accuracies.
- the wheel disc has a one-piece rim formed between the spokes in a known manner with a rim bed, an outer and an inner rim flange and a spoke having a wheel disc, which inserts either form a plane with the outer surface of the wheel disc or below that outer surface of the wheel disc are arranged, that is, are not raised above the wheel disc.
- Various types of attachment of the visible inserts to the wheel disc are conceivable, for example a snap or screw connection.
- the screws holding the visible inserts on the wheel disc are arranged concentrically to the fig axis, the number of screws per insert should be at least two.
- the adhesive then also serves as a sealant against the ingress of dirt particles or moisture.
- the visible inserts can be fastened to the wheel disc by means of visually arranged screws, it also being conceivable to provide the screws only for purely optical reasons, without them having a fastening effect.
- the spokes can be formed perpendicular to the rim axis and form a substantially flat wheel disk arranged far outside. This appears - 4 - also as a wheel disc of larger diameter. This effect can be enhanced by the fact that its hub area is sunk and further depressions with holes for fastening screws are formed in this depression area. As many fastening screws as spokes are preferably provided, the fastening screws being arranged in each case in the region between the rim axis and a spoke.
- the inserts can cover the area of the rim bed facing the rim axis between the spokes. However, they can also be designed so that they cover this area and the spoke flanks.
- the fig's appearance can be changed in a simple manner and can be adapted to a vehicle, also according to the wishes of the user.
- the inserts can be made of metal, for example magnesium, aluminum or stainless steel, but also made of plastic. Inserts made of carbon fiber or carbon are also conceivable.
- the inserts offer the possibility of coloring, for example in the body color.
- the inserts can be provided with cavities for further weight reduction.
- the inserts are chrome-plated.
- the spokes extend from the hub to close to the outer rim flange. This has the advantage that the rim looks larger.
- Fig. 1 shows a light alloy rim with a rim bed 1 with an outer rim flange 2 and an inner rim flange 3, with a wheel disc 4, with an outer surface 10 which has five spokes 5 (Fig. 2a, 3a), and not Screw elements 6, which are shown in more detail and are known, are arranged concentrically to the rim axis A.
- the rim is made in one piece.
- the spokes 5 are arranged perpendicular to the rim axis A and extend from the hub area 7 to the outer rim flange 2, the wheel disk 4 being essentially flat.
- Visible plastic inserts 8 are arranged between the spokes 5, which are detachably fastened to the rim base 1 with the screw elements 6 and form a plane with the outer surface 10 of the wheel disc 4. These inserts 8 cover the side of the rim base 1 facing the rim axis A between the spokes 5 and the flanks of the spokes 5.
- FIG. 2a shows the arrangement in perspective and FIG. 2b shows a single insert 8 with bores 13 for the screw elements 6.
- FIG. 3a Another embodiment is shown in Fig. 3a. In this case, only the side of the rim base 1 facing the rim axis A between the spokes 5 is covered with an insert 9 each.
- the hub area of the light metal rim is recessed and provided with holes for fastening screws 12 in the area between the central recess 11 and the rims 5.
